Serum levels of intact parathyroid hormone in elderly patients with hip fracture living at home

Abstract

The serum levels of intact parathyroid hormone and cholecalciferol metabolites have been measured in patients with hip fracture above 70 years of age admitted to hospital from home-living conditions and compared with serum levels in age- and sex-matched home-living control subjects. It was found that patients with hip fracture had significantly lower levels of calcidiol (29.7±15.9 vs 46.0±27.8 nmol/l) and calcitriol (63.6±25.0 vs 91.1±39.5 pmol/l) with no difference in serum levels of intact parathyroid hormone (47.2±2.1 vs 5.3±3.3 pmol/l). The data suggest that secondary hyperparathyroidism is not an important risk factor in our population of patients with hip fracture.
